Beam and segment launching gantries are specialised equipment used in bridge construction with prefabricated elements such as prestressed or reinforced concrete beams and slabs.
Technology benefits
- Fast execution – significantly reduces construction time.
- Controlled quality – elements are produced in factory settings under optimal conditions.
- Less weather dependency – most of the work is carried out off-site.
- Safety – less time and reduced exposure of workers at height.
- Sustainability – less material waste and fewer disposable formworks.
- Lower traffic impact – ideal for interventions over existing roads (reduces interruption time).
Services
Prefabricated Components Used
- Prefabricated beams and slabs (in prestressed or reinforced concrete)
- Complete modular elements
Métods de colocación in situ
- Using large cranes, installed next to the bridge or on mobile platforms;
- Using beam/segment launching gantries, especially useful in hard-to-access areas (deep valleys, railway lines, operational motorways, or even watercourses);
- By modular road transport with lifting.
